Steam Web API/Feedback
Suggestions
Provide more information about player profiles (like the old XML interface)
ISteamUser should either have another method to get the entire information about a player (e.g. friends, groups and games) or GetUserSummaries should provide these (with an optional argument):

Provide games information
There should be something like ISteamGame to retrieve information about every game available on Steam. One method to get all games and one for detailed information about one game, e.g. appid, name, release date, publisher, achievements, store link, price (depending on the country code) etc. and all subIDs (packages) they're included in.
Equally there should be something like ISteamPackage to retrieve information about every package available on Steam. One method to get all packages and one for detailed information about one package. e.g subid, name and all appIDs of games, that are included and price (depending on the country code).
